Geoffrey Wheatcroft's hugely entertaining and well researched history of the Tour de France is already established as the definitive account of cycling's greatest event. Since the book was last published in 2007, much has changed. Bradley Wiggins' historic victory in 2012 - the first Briton ever to secure the yellow jersey - brought him a knighthood and garnered more interest in the race than ever before. Yet the months after were dominated by an even bigger story, as Tour legend and seven-time winner Lance Armstrong was stripped of his titles and confessed on Oprah to doping in each of his victories.

Suddenly, everything that we thought we knew had happened was no longer true. In this new and comprehensively revised edition of the book, Wheatcroft not only brings his story of the Tour fully up to date to mark the race's 100th running in 2013, he also reflects on the changes brought about by the scandals that have rocked the sport to its core. Yet for all the controversies of modern times, he vividly captures the essential glory and romance of the heroes who battle to conquer one of sport's greatest challenges.
